ACETYLENE-GAS BURNER.

SPECIFICATION forming,` part of Letters Patent No. 619,843, datedFebruary 21, 1899.

Application filed January 25, 189B. Serial No. 667,889. (No mdel.)

To all whom it may concern:

Be it known that I, ERNST HEINRICH J ULIUs SGHLKE, engineer, a subjectof the Emperor of Germany, and a resident of No. 94 Leipzigerstrasse,Berlin, in the Empire of Germany, have invented certain new and usefulimprovements in devices in connection with acetylene-burners forpreventing the formation of soot, of Which the following is an eX- act,full, and clear description.

This invention relates to a device which is applied to acetylene=burnersfor preventing the formation of soot. Hitherto the great disadvantage inconnection with acetylene-burners has been that at low gas-pressure theame formed soot at the outlet, so that particles of soot accumulatedthere, whereby the action of the burner was impaired and the burner waseventually rendered altogether useless.

Now the object of this invention is to avoid this drawback by providingabove the outlet of the acetylene-burner a disk or plate which isprovided with an opening corresponding to the outlet of the burner. Thisdisk or plate acts in such manner that the outgoing stream of gas is setinto flame only at the opening in the disk or plate-z'. e., above thesame- Whereas in the space between the opening of the burner and theguard-plate or recessed disk an ignition or formation of iiame does nottake place, in consequence of which particles of soot cannot accumulateat the outlet of the burner and an obstruction in the narrow passage ofthe burner is impossible. vBy the arrangement of the cut-out guard-plateor recessed disk an increase of the supply of air is also attained inconsequence of the stronger draft in such manner that the acetylene gasis completely consumed, and even at lovT gas-pressure the formation ofsoot is entirely avoided. In the accompanying drawings such a device isshown by way of example.

Figure 1 is a longitudinal section of the upper part of a burner whichis provided With the guard-plate or recessed disk. Fig. 2 is a planview, and Fig. 3 is a perspective view of the guard-plate and sleeve forattaching it to the burner-tube.

The burner-tube a is inclosed by a sleeve b, having an arm b', on whichthe guard-plate -or cap c is provided. This guard-plate or cap consistsof a disk or plate c, having an open ing c', which is arranged justabove the outlet d of the burner and corresponds therewith. The outlet dis of funnel shape.

Having now particularly described and ascertained the nature of the saidinvention, I declare that what I claim, and Wish to secure by LettersPatent, is-' In an acetylene-gas burner, the combination of aburner-tube having at its outlet the form of a funnel with aplate havingan opening arranged above the burner-outlet, such opening having aboutthe same diameter as that of the end of the extension of the burnertube.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
